I'd like to be less socially anxious/awkward, but still I value my introversion.
Neither of you come off as socially awkward to me.
The anonymity of the interwebs cause people to behave differently than they normally would. Also, posting text is easier than talking in person for many people because it gives them time to think about what they are saying without the pressure of an immediate response being needed.
Interesting, because the opposite occurs for me. In person I can (and do) speak off the cuff on just about any topic, but here on the forum I'll intentionally decide not to post sometimes because I know that if I start typing, the freedom of communicating through text often causes me to spend an inordinate amount of time perfecting everything I say, as if I was writing a term paper or something.
